Not bad teachers are all one-on-one, making achievements. It is of great help to children, not only in the effect of making up lessons, but also in the cultivation of study habits and the formulation of study plans. I only know that the teacher who teaches my children is very good, and other teachers are not very clear, but when the children are with me, they all say that the teacher is good. I recommend my friend's children to cram school, and his children's grades have also improved.
